There are numerous barcode fonts out there. All you need to do is
install some on your machine and then place text on your page using the
barcode font as the font for the text.
We use the Carolina barcode fonts for 3 of 9 encoding:

In our case, we design from XML schemas, so we can't see sample data in
the designer, so we don't see the barcodes as they ultimately appear on
the reports, but they do appear on the reports, and they do scan.
